Seems like newly introduced <On> tag for setting value depending on platform doesn't work on UWP with .Net native tool chain enabled:
For example if we set TextColor this way :
value is not applied to the control,
but if we declare it using deprecated <OnPlatform> tag
everything works fine
This behavior is true for Xamarin.Forms 126.96.36.199 still not fixed in Xamarin.Forms 188.8.131.526-pre6
Sample solution is attached
Thank you for the reproduction. My machine is personally not showing a difference regardless of whether the native tooling is on or not, but I am on an insider build of Windows 10 so that might have something to do with it. iOS does work for both labels, however, to compare. I'll set this to confirmed for now until further investigation.
I have the same issue
I tested this with Xamarin.Forms 2.4.0-pre2 and it appears to be fixed. Note that the "Windows" platform has been split into "WinRT" and "UWP". When using <On /> and "UWP" in the sample project, both Labels now look the same even when "Compile with .NET Native tool chain" is enabled.
